Residents in certain Port Huron neighborhoods are receiving letters this week from the St. Clair County Health Department about elevated lead levels in the area. The health department says soil samples in the neighborhoods on the west side of town have shown higher than normal lead levels. As a precaution, the health department will be offering free blood lead level testing for those who may be affected. The blood tests will occur at the Harrison Center located on 15th Street in Port Huron on June 26th. Those living within the boundaries of 12th Street, Howard Street, Water Street, and the west city limits are urged to get their blood lead levels checked. The St. Clair County Health Department also says officials from the Michigan Department of Environmental Quality will continue soil samples in the area. If your property is included in the area, the DEQ will be sending you a letter asking for the property owner’s permission to check ground lead levels. Health officials say most people do not show symptoms of lead poisoning and testing is the only way to know if you are affected.
